Room-temperature condensation in whispering gallery microresonators assisted by longitudinal optical phonons
Christof P. Dietrich, Rüdiger Schmidt-Grund, Tom Michalsky +2
We report condensation of hexagonal whispering gallery modes (WGM) at room temperature in ZnO microwires that embody nearly perfect polygonal whispering gallery microresonators. Th…
Vortex-antivortex dynamics and field-polarity-dependent flux creep in hybrid superconductor/ferromagnet nanostructures
M. Lange, M. J. Van Bael, A. V. Silhanek +1
Vortex-antivortex arrays that are created in a type-II superconducting film by lattices of ferromagnetic dots with perpendicular anisotropy have been investigated. The highest crit…
Phase diagram of a superconductor / ferromagnet bilayer
M. Lange, M. J. Van Bael, V. V. Moshchalkov
The magnetic field (H) - temperature (T) phase diagram of a superconductor is significantly altered when domains are present in an underlying ferromagnet with perpendicular magneti…
Field-dependent Vortex Pinning Strength in a Periodic Array of Antidots
A. V. Silhanek, S. Raedts, M. Lange +1
We explore the dynamic response of vortex lines in a Pb thin film with a periodic array of antidots by means of ac-susceptibility measurements. For low drive field amplitudes, with…
Nanoengineered magnetic-field-induced superconductivity
M. Lange, M. J. Van Bael, Y. Bruynseraede +1
The perpendicular critical fields of a superconducting film have been strongly enhanced by using a nanoengineered lattice of magnetic dots (dipoles) on top of the film. Magnetic-fi…
Magnetic-domain-controlled vortex pinning in a superconductor/ferromagnet bilayer
M. Lange, M. J. Van Bael, V. V. Moshchalkov +1
Vortex pinning in a type-II superconducting Pb film covering a Co/Pt multilayer with perpendicular magnetic anisotropy is investigated. Different stable magnetic domain patterns li…
